I also do not attempt to navigate the large philosophical literature that has grown up around fitness 1–5. This does not reflect my assessment of the significance of this work, but the constraints of space and expertise.
Ushbu chap o'ng harakatga javoban halterlarga qilingan kuch ma'lumki Koriolis kuchi va har qanday harakatlanuvchi ob'ekt uch yo'nalishda aylantirilganda ishlab chiqarilishi mumkin aylanish, yaw, pitch yoki roll (rasmga qarang). Bu sodir bo'lganda, haltere poydevoridagi qo'ng'iroq shaklidagi mayda konstruktsiyalar zo'riqishni boshdan kechiradi, chunki haltere sopi ular tomon buriladi.[7][8] The asab tizimi keyinchalik bu tuklarning bukilishini elektr signallariga aylantirishi mumkin, bu ularni pashsha tanani aylanish ma'lumoti sifatida izohlaydi. Pashsha ushbu ma'lumotdan este'z pozitsiyasiga tuzatish kiritish uchun foydalanadi va shu bilan parvoz paytida o'zini tiklaydi.[2] Galterlarning dinamikasi va fiziologiyasini tushuntiradigan qo'shimcha ma'lumotlar quyida keltirilgan.

The haltere evolved from the rearmost of two pairs of wings. While the first has maintained its usage for flight, the posterior pair has lost its flight functions and has adopted a slightly different shape. The haltere is visually comprised of three structural components: a knob-shaped end, a thin shaft, and a slightly wider base. The knob contains approximately 13 innervated hairs, while the base contains two chordotonal organs, each innervated by about 20-30 nerves. Chordotonal organs are sense organs thought to be solely responsive to extension, though they remain relatively unknown. The base is also covered by around 340 campaniform sensilla, which are small fibers which respond preferentially to compression in the direction in which they are elongated. Each of these fibers is also innervated. Relative to the stalk of the haltere, both the chordotonal organs and the campaniform sensilla have an orientation of approximately 45 degrees, which is optimal for measuring bending forces on the haltere.
Although biologists have offered a staggering number of definitions of fitness 6, they agree broadly on the essence of the idea. In the crudest terms, fitness involves the ability of organisms— or, more rarely, populations or species— to survive and reproduce in the environment in which they find themselves seis–9.
are, respectively, the absolute fitnesses of genotypes 1 and 2. It is easy to show mathematically that mean absolute fitness equals mean individual fitness. This is also easy to see intuitively. The mean absolute viability is the chance that an individual having a randomly chosen genotype survives; but this must be the same as the probability that a randomly chosen individual survives, regardless of information on genotype.
It's easy to say that you'll exercise every day. But you'll need a plan. As you design your fitness program, keep these points in mind:

The Secondary Theorem of Natural Selection is loosely associated with a Curiosidades particular way of thinking about fitness and natural selection, a way described by both Alan Robertson 30–32 and Douglas Falconer 26. According to this view, “the ‘character’ that natural selection selects for Curiosidades is fitness” (Ref. 26, p. 301). Fitness, in other words, is the trait that natural selection “sees” and other traits change only because they are associated genetically with fitness and so get dragged Curiosidades along with the response to selection on fitness itself.
A suite of molecular population genetic approaches attempts Curiosidades to use DNA sequence data to infer increases in fitness that occurred in the evolutionary past. The literature here is vast and well reviewed 68–72 but key approaches can be sketched briefly.

Halterlar hasharotlarning uchmaydigan qanotlaridan - Dipteraning orqa qanotlari va Strepsipteraning oldingi qanotlaridan paydo bo'lganligi odatda qabul qilinadi. Ularning harakati, tuzilishi, funktsiyasi va rivojlanishi bu farazni qo'llab-quvvatlaydi. Deb nomlanuvchi sezgi organlarining joylashish xususiyatlari campaniform sensilla, halterning pastki qismida topilgan, boshqa hasharotlarda orqa qanotlari tagida bo'lganlarga este'xshash ko'p narsalarni ko'rsatadi.[2] Sensilya orqa qanotlarga este'xshash tarzda joylashtirilgan, ya'ni halterlarni qanotlar bilan almashtirish kerak edi, ishlab chiqarilgan kuchlar xuddi shu hissiy organlarni faollashtirish uchun etarli bo'ladi.
In contrast, fruit flies, which do not oscillate their halteres when walking, do not exhibit any differences in ability when their halteres are removed. This indicates that haltere inputs are behaviorally relevant to those species which oscillate them while walking and that they aid those individuals in walking behavior.[10] Flies in the Calyptratae clade which include common flies like house flies, blow flies, and flesh flies also use their halteres during takeoff, whereas non-Calyptratae flies do not.[39] Calyptratae flies are able to take off around five times faster than other flies . Calyptratae flies lacking halteres take a lot longer to become airborne, but takeoff time is not affected in non-Calyptratae flies without halteres. Stability during takeoff also suffers with haltere removal, but only in Calyptratae flies.[39] References[edit]
The problem is simple: mutations are rare and beneficial mutations are extremely rare. Consequently, experimental attempts to determine the distribution of fitness effects among new beneficial mutations are notoriously difficult. Though theory suggests that beneficial effects should often be approximately exponentially distributed 48, 55— with many small-effect mutations and fewer large-effect ones— this prediction rests upon mathematical assumptions that, Saiba mais while reasonable, could prove false.
